Although urodynamic testing is frequently performed as part of the evaluation of SUI, the benefits obtained by performing such testing have not been well defined. Advocates of a “minimalist” approach argue that direct observation of stress incontinence on physical examination […]
A new urodynamic measurement system for urethral retroresistance pressure (URP) has been described. URP is defined as the pressure required to achieve and maintain an open urethral sphincter and is measured by occluding the urethral meatus with a cone-tipped plug […]
Historically, the first urodynamic parameter measured to characterize stress incontinence was the resting urethral pressure profile (UPP), which was based on the idea that continence is maintained as long as urethral pressure exceeds intravesical pressure. It was thought that measuring […]
Introduction The American Urological Association has published guidelines for the surgical management of female stress urinary incontinence (1). According to these guidelines, the objective demonstration of stress urinary incontinence should be documented prior to initiating surgical therapy. This can be […]
Patients with neurogenic OAB tend to have severe symptoms that are more difficult to treat pharmacologically. It is not immediately clear that the overactive contractions experienced by patients with neurological conditions are necessarily of greater amplitude or occur earlier during […]
Although no clear criteria exist for differentiating neurogenic from idiopathic DO, it has been suggested that unstable bladder contractions occurring as a result of neurological disease may be more likely to result in urge incontinence (17) and have a greater […]
After the decision is made to proceed with urodynamic testing, the next consideration is the type of testing to be conducted. Most current urodynamic machines offer only multiple-channel testing because single-channel testing is prone to considerable artifacts. In general, because […]
Introduction Urodynamic studies (UDS) generate information about bladder function that, currently, no other testing can provide. Though clearly not necessary to evaluate all lower urinary tract symptoms (LUTS), UDS can be useful when confronted with situations in which the normal […]
The workup described constitutes the basic office assessment (BOA) of UI; it is generally accepted. However, the role of urodynamics in the evaluation of patients with UI is controversial. This is because the true impact of urodynamics on clinical diagnosis, […]
Patient histories regarding frequency and severity of urinary symptoms are often inaccurate. A more reliable indicator of symptoms is a fluid intake/voiding diary, which should be distributed to patients. They would be instructed to document in it the amount and […]
